Introduction
The statement regarding electrons revolving around the nucleus is a key concept in atomic theory. It was primarily articulated in the context of early atomic models.
Rutherford's Contribution
- Ernest Rutherford conducted his famous gold foil experiment in 1909, which led to the discovery of the atomic nucleus.
- He proposed that atoms consist of a dense nucleus surrounded by electrons. This marked a significant shift from the earlier plum pudding model by J.J. Thomson.
- Rutherford suggested that electrons orbit the nucleus much like planets orbit the sun, which indicated that they are not stationary but rather in motion.
Electron Behavior in Rutherford's Model
- Electrons in Motion: Rutherford's model implied that electrons have kinetic energy and revolve around the nucleus, providing a dynamic view of atomic structure.
- Circular Paths: While he did not specify the exact nature of their paths, the idea of circular or elliptical orbits became a foundational concept for later models, particularly Bohr's model.
Impact on Atomic Theory
- Rutherford's insights paved the way for Niels Bohr to further refine the atomic model, introducing quantized orbits.
- The concept of moving electrons was essential in understanding atomic behavior, chemical bonding, and the nature of matter.
Conclusion
In summary, the statement about electrons revolving around the nucleus can be attributed to Ernest Rutherford, making option 'B' the correct answer. His groundbreaking work laid the foundation for modern atomic theory and our understanding of atomic structure.
